- The end walls 11' and 12' oi'each of the recesses 11 and 12' are preferably tapered upwardlytoward thetop and wedge blocks 18 secured by chains-19 to the beams 6 and 7 are adapted to be inserted between the tapered end walls of the casting and the ends of the flapper blocks .tojhold'the said blocks in adjusted positions.

-Keeper blocks 20 are" rigidly seciued to vthe side wallsof the container 3 and are 22, each provided with a rectangular recess formed -with right angularly"projecting flanges 21 which are arranged tofengage the inward side faces of the flapper blocks to hold the containers rigidly in'position from lateral movement on the dollytruck.

Attached to the end beamsl are castings 23 in the top and open at the inner. side.

A single flapper block 24 otsi'niilar constructionto the blocks 15 is arranged ineach of these recesses and secured therein by a horizontal pin 25 and'w'edge blocks 26 sim:

ilar to the wedge blocks 18 are arranged for securing the flapper blocks 24 in place.

Keeper blocks- 27 similar to the keeper blocks 20 are provided on. the container...

I The'keeperblocksare so arranged that they will match with the flapper. blocks on either the end or centreiblock beams whichever way the container may beplaced in position. i

The central block members are supported upon the pairof beams 6 and? and in' order to provide ample support for'the end-beams 4 I providethe angle plate brackets 28 which are secured underthe outer flange of the beam and to the sill 29 of the dolly truck.

In-the use of this equipment, when it is desired to place a container upon a car equipped with a dolly truck, the wedge blocks are removed from engagement with the flapper blocks on both sides ofthe car the. container is to be entered and the flapper blocks are turned upwardly the ones at the other side of the car beingle'ft down.

The container is then rolled on to the track-ways 2 so that the lip flanges 5, 6 and 7' engage the flanges9 oi the angle brackets on the container and when the keeper blocks at the far side of the container engage the flapper blocks the container is brought to rest. V

The flapper blocks on the loading side are I thenthrown downand' the wedge blocks are then inserted and*driven'home to foroe'the. ends of theflapper blocks snugly up against the keepers back of their retaining flanges.

The flapper blocks on both sidesof the car are preferably thus'adjusted so as to providean additional guard against any move ment of the container longitudinally ot the car in the event of the locking flanges 9 having any loose play in their contact with the retaining lips oi thelock beams.

The retaining lips of the lock beams hold the containers hrmly down upon the deck of the dolly truck and the flapper blocks lock the containers securely from side movement as well as from further end movement. E

The construction of locking members herein described is extremely simple but it is very 'i effective in. use. and is strong and rugged and will withstand the. terrific shocks imparted thereto in railway traffic.

VVhena container is to be removed from adolly truck it is merely necessary to remove the. wedge blocks on the side from which the container, is to be removed, then turn theflapper'blocks upwardly and the container is then free. v

The flapper blocks'are here'shown with sides. These lugs are preferably provided I 5 lugs 30 projecting upwardly from the topto prevent the flapper blocks from beingleft v in an unlocked position and the flapper blocks are of such length that they will engage the keepers 'on the container whether the wedges are inserted} behind them or not.

This provides agairistKcarelessness on the part of those loadingthe containers on to the cars-, permitting ,a containerjto be left unlocked. I V

What Icl'aim as my invention is 1. In means for locking freight containers', the combination with a truck onwhich the container is mounted, of locking memers mounted on the container adapted 'to en'- gage said locking members to hold the container from. endwise movement, andinter-v lOOkIIIg means secured on the container and on'the truck adapted to hold'the container from longitudinal movement oh the truck or from tipping. y

2. In means torsecuring freight containers,. the combination with the truck on which the container is mounted, of flange members extending longitudinally of the containers and arranged on thefs'ides thereof at the loo -bers pivotally mounted on thetruck, keepbottom intermediate of. the length thereof.
